The egotistical bastard was angry because he went on and on as a reported waited to give a remote report. Jackie said " You have JR on your shoulders"...Radnich blew up!. "I know what the hell I have!..I made you!"."I dont need YOU to tell me how to do my show". Then,they cut to JR. And you can only imagine what fireworks off air between the two anchors when Stone was cut off...and they went to commercial.
I've seen that cut to commercial before as a "time out" when two anchors just went at each other..or guests on shows..that kind of thing.
If that was shtick,then Jackie must be desperate to be made to look like a peon of the set.
